Following up on the original “The Black Mamba” trailer previewing Kobe Bryant’s upcoming Robert Rodriguez-directed film comes a second trailer. The second part maintains a similar approach with the addition of one key element. Kanye West makes an appearance as “The Boss” in what should make for an even more interesting final product. A full launch is slated for Saturday, Feb. 19, 2011 at 1:00 a.m. PST.
